Removal
1.) Remove the cotter pin from the propeller shaft and discard.
2.) Wedge a piece of 1" x 4" wood between the propeller blade and the starboard side of
the strut and rudder.
3.) Remove the nylon locknut and discard.
Use a propeller puller to remove the propeller, then remove the key from the keyway.
Inspect the keyways and key for any damage.
Installation
Before installing the prop, look at the keyway on the shaft and in the propeller. The key
should slide freely in both keyways. DO NOT use the prop nut to advance the prop onto
shaft.
If the key has slight damage or burrs, remove them by filing the flat sides or replace the
key. DO NOT file the key beyond its normal shape or size.
1.) Rotate the shaft until the keyway is “up.”
2.) Place the key in the shaft keyway. Align the keyway in the prop to the key. The prop
will only slip on in one direction. Once the prop starts to go on the shaft, push the
propeller “solidly” on the shaft and make sure you feel that it is seating properly.
3.) Wedge a piece of 1" x 4" wood between the propeller blade and the port side of the
strut and rudder.
4.) Install a new nylon locknut and torque the nut to maximum of 30 ft-lbs (40.7 N•m).
5.) Install new cotter pin. Bend the retaining ends of the cotter pin in the opposite
directions. Make sure the cotter pin is snug and cannot rotate.
Malibu Exclusive Adjustable Rudder System
Your Malibu steering is custom calibrated at the
Malibu factory at the time of manufacturing. However, it may be
necessary from time to time to adjust the steering due to normal
operations. Malibu Boats’ unique adjustment feature allows custom
calibration to your specific driving needs. The Malibu Adjustable
Rudder system allows you to increase or decrease the amount of load
that is typically on the steering system.
If it is determined that your rudder needs adjustment, you can do so
by adjusting tunable feature located on the rudder surface. Locate
the 1/8" set-screws. Loosening the set-screws will release the
adjustment tab. If your boat pulls to the right, turn the tab to the
right 1/8th to 1/4". Do not move beyond this point. Only minor adjustments are needed to
make a correction. Note that it may take more than one adjustment to get the desired
setting. Tighten the set-screws when adjustment is completed.
